无油滑动轴承是在滑动摩擦下工作的轴承。无油滑动轴承通过设计实现自润滑，工作平稳、可靠、无噪音。在液体润滑条件下，滑动面被润滑油分离，不直接接触，可大大减少摩擦损失和表面磨损。油膜还具有一定的减振能力。
Oil-free sliding bearings are bearings that work under sliding friction. Oil-free sliding bearing achieves self-lubrication through design, and works smoothly, reliably and noiselessly. Under the condition of liquid lubrication, the sliding surface is separated by lubricating oil without direct contact, which can greatly reduce friction loss and surface wear. The oil film also has a certain ability to reduce vibration.
但起动摩擦阻力较大。由淮安NSK轴承支撑的部分称为轴直径，与轴直径匹配的部分称为轴承套。为了提高轴瓦表面的摩擦性能，在轴瓦内表面浇注的减摩材料层称为轴瓦。
But the starting friction resistance is bigger. The part supported by Huaian NSK bearing is called the shaft diameter, and the part matched with the shaft diameter is called the bearing sleeve. In order to improve the friction performance of the bearing bush surface, the anti-friction material layer poured on the inner surface of the bearing bush is called the bearing bush.
轴瓦和衬套的材料称为滑动轴承材料。在低速和重型应用中，很难进行维护和润滑。
The material of bearing bush and bushing is called sliding bearing material. It is difficult to maintain and lubricate in low speed and heavy applications.
滑动轴承具有结构简单、制造方便、径向尺寸小、吸收润滑油膜振动能力强、冲击载荷大、运行稳定、无噪音等优点。在保证液体摩擦的条件下，轴能长时间高速运转。适用于精mi、高速、重型旋转场合。
The sliding bearing has the advantages of simple structure, convenient manufacture, small radial dimension, strong ability to absorb vibration of lubricating oil film, large impact load, stable operation and no noise. Under the condition of guaranteeing liquid friction, the shaft can run at high speed for a long time. It is suitable for precision mi, high speed and heavy rotary occasions.
淮安NSK轴承主要用于工程机械轴套、销套接头（挖掘机、推土机、装载机）、重型平衡轴套、摩托车减震器轴套、液压工业、液压齿轮泵轴套、气缸、缸套、注塑机、硫化机、模具工业、弹性模型、汽车等。活动模导板，水力机械涡轮，锻造。工业、冲压机、冶金工业。
Huaian NSK bearings are mainly used in construction machinery axle sleeve, pin sleeve joint (excavator, bulldozer, loader), heavy balance axle sleeve, motorcycle shock absorber axle sleeve, hydraulic industry, hydraulic gear pump axle sleeve, cylinder, cylinder liner, injection moulding machine, vulcanizer, mould industry, elastic model, automobile, etc. Movable Die Guide Plate, Hydraulic Machinery Turbine, Forging. Industry, stamping machine, metallurgical industry.
圆柱滚子轴承的特点是圆柱滚子和滚道称为线性接触轴承。承载能力大，主要承受径向载荷。圆柱滚子轴承非常适合高速旋转，因为它们在滚子和环的固定边缘之间的摩擦非常小。圆柱滚子淮安NSK轴承是内外环的可分离结构。
Cylindrical roller bearings are characterized by cylindrical roller and raceway called linear contact bearings. The load-bearing capacity is large, and it mainly bears radial load. Cylindrical roller bearings are very suitable for high-speed rotation because they have very little friction between the fixed edges of the rollers and rings. Cylindrical roller Huaian NSK bearing is a separable structure of inner and outer rings.
轴承圆柱滚子轴承可分为内环或外圈单侧和双面圆柱滚子轴承，其内环和外圈可相对于轴线移动，因此可作为zi由端轴承使用。内外圈一侧带有双挡块，另一侧带有单挡块的圆柱滚子轴承，在一个方向上可以承受一定的轴向载荷。一般来说，钢板冲压保持架或整体保持架与进步党汽车系统集成在一起。但有些人用聚酰胺做笼子。
Bearing cylindrical roller bearings can be divided into inner ring or outer ring single-sided and double-sided cylindrical roller bearings, whose inner ring and outer ring can move relative to the axis, so they can be used as Zi by end bearings. Cylindrical roller bearings with double baffles on one side of inner and outer rings and single baffles on the other side can bear certain axial loads in one direction. Generally speaking, the sheet metal stamping cage or integral cage is integrated with the Progressive Party automobile system. But some people use polyamide as cages.
轴承圆柱滚子淮安NSK轴承在滚子和滚道之间具有线性或向下接触。它们具有较大的径向承载力。适用于重载和冲击载荷。摩擦系数小，适用于深沟极限转速附近的高速滚珠轴承。它们对轴或座的加工要求很高。Le很高。
The bearing cylindrical roller Huaian NSK bearings have linear or downward contact between the roller and raceway. They have large radial bearing capacity. It is suitable for heavy load and impact load. The friction coefficient is small, so it is suitable for high-speed ball bearings near the limit speed of deep groove. They have high requirements for the processing of shafts or seats. Le is very high.
